↵* Incidence rates computed for SCCS participants aged 45–64, 65–79, and 40–79 years for comparability with the ARIC, CHS, and MESA cohorts, respectively. In addition, the rates are standardized to the age distribution of the SCCS study participants within these age ranges.

↵† The tabulated values are computed from values presented in Arnold et al5 and standardized to the age distribution of CHS participants.

↵* By design, participants enrolled in MESA were free of cardiovascular disease at baseline so the prevalence of myocardial infarction and stroke at baseline in this cohort may be best described as not applicable.

↵† The baseline data for the FHS pertains whenever available to both the original cohort and the offspring cohort given this larger sample was used to compute HF incidence rates referenced in the article. In the absence of such data, we have presented data from the original cohort (or subsamples thereof) as a proxy and indicated so in each case.
